actual people and events

Not sure hoe to put this, but I want to find some works that follow actual people or events. this guy that I know said that manga only covers fictionand things and stuff that relates to japan.

HistoryIt can be anything from historical events and people to survival tactics and cultures so long as it was actually used. eg. Red River had cultural interaction between the Hitite and Egyptian empires as well as historical references

SportsIf it educates you on the subject, involves tactics or famous people that would be great. eg. Area no Kishi

OtherI cant' think of much else, maybe school subjects or work fields, even having an english author would do. But if you can think of anything else I would love to see them.

bakuman explains world of manga from writers side aoi bungaku episode 1-4(story one)- it is based of a ficional novel but it is realistic because of how it related to the authors situation which is explained at the beginning of each episodegin no saji explains a few things related to farming

Basically you want to know about any educational series not pertaining to Japanese culture?

Mori Kouji apparently researches the subjects of his manga beforehand and tries to educate his readers. Holyland had information on different type of martial arts, but I don't know how accurate the information is.

Most cooking or food-related series, like Addicted to Curry and Bartender, has various information on their subjects, but I don't know how accurate that information is as well.

Crimsons has a bunch of information on marine life and seems fairly accurate from what I know.

Futari Ecchi has sex education apparently but I was not interested enough to check it out myself.

[Basically you want to know about any educational series not pertaining to Japanese culture?]

-yes! this was what i was looking for, anything that could add to your knowledge whether it would be useful in life or not. I found that a lot of the history related suggestions were just good to know and the ones related to cooking, agriculture and survival might help in future.

There weren't any english authors as I had hoped, but then again, I guessed that a majority of them would be in the Josei section so it wouldn't help anyway.

For sports try All Rounder Meguru, it's about mixed martial arts and is very very realistic. I actually understand MMA a little bit now that I've read it. Baby Steps is a fairly realistic and educational manga about tennis.
